Amy Winehouse cuts all ties to former collaborator Mark Ronson

Amy Winehouse says her one-time pal and collaborator Mark Ronson is “dead to me,” accusing the super-producer of taking credit for her fame.

Ronson helped Winehouse achieve a worldwide smash with her Grammy-winning 2006 release Back to Black, and the pop star returned the favor the following year by singing Valerie for the DJ’s covers compilation Version.

The pair teamed up again earlier this year to record a song for a new Quincy Jones tribute record, but their relationship has since soured. And Winehouse has blasted Ronson for using her solo success as a launchpad for his own blossoming career.

Taking to Twitter, she writes, “Ronson you’re dead to me; one album I write and you take half the credit – make a career out of it? Don’t think so BRUV.”

It is thought Winehouse’s comments stem from an interview Ronson gave on Friday in which he told musician-turned-TV presenter Jools Holland he had “created the tracks” on Back To Black from the singer’s demos.
